FIELD OF THE TECHNOLOGY

At least some embodiments disclosed herein relate to selection and/orarrangement of content for presentation to a user. In one specificembodiment, the content is an exercise video playlist that a person canfollow on a computing device (e.g., an Apple iPad device).

BACKGROUND

Exercise helps to maintain a healthy lifestyle. Many individuals want toparticipate in an exercise program. A successful exercise program istypically tailored to a fitness level of an individual and aimed atassisting the individual to achieve one or more specific fitness orexercise goals.

Sports trainers are available to assist individuals in developingexercise programs appropriate for their individual fitness levels andtheir specific fitness or exercise goals. Hiring such professionals,however, can be expensive. Furthermore, the busy schedules of manyindividuals make it difficult for these individuals to set aside time tomeet with a fitness professional on a regular basis. Thus, manyindividuals fail to use the services of fitness professionals, and neverachieve the benefits that can be obtained from an exercise programtailored, for example, to one's fitness level or areas of exerciseinterest.

DETAILED DESCRIPTION

The following description and drawings are illustrative and are not tobe construed as limiting. Numerous specific details are described toprovide a thorough understanding. However, in certain instances, wellknown or conventional details are not described in order to avoidobscuring the description. References to one or an embodiment in thepresent disclosure are not necessarily references to the sameembodiment; and, such references mean at least one.

Reference in this specification to “one embodiment” or “an embodiment”means that a particular feature, structure, or characteristic describedin connection with the embodiment is included in at least one embodimentof the disclosure. The appearances of the phrase “in one embodiment” invarious places in the specification are not necessarily all referring tothe same embodiment, nor are separate or alternative embodimentsmutually exclusive of other embodiments. Moreover, various features aredescribed which may be exhibited by some embodiments and not by others.Similarly, various requirements are described which may be requirementsfor some embodiments but not other embodiments.

In one embodiment, a video playlist is generated using an fitnessapplication executing on an iPad (an exemplary application is identifiedas “FitMix” herein merely for illustration). The fitness applicationdynamically generates a workout video based on user inputs. Within theapplication, a user defines parameters such as, for example, the desiredtime length of workout (e.g., total minutes), workout equipment that isdesired for use or available to the user, and a preferred fitnessinstructor(s) (i.e., the instructor leading a given video clip).

In one embodiment, using software logic, the fitness application selectsdistinct exercise video clips (e.g., approximately 30-90 seconds each)from a video clip database and arranges the clips into a playlist. Theplaylist of video clips is then displayed to the user as a seamless,full-length workout video that complies with the user-definedparameters.

In one embodiment, the fitness application generates a wide variety andnumber of user-customized workout videos (e.g., many permutations ofvideo clips may be generated). Typically, the user will rarely see thesame identical workout video again as each video will have somevariation. A number of factors promote this high degree of variability:the use of user-defined parameters, the randomization of clip-selectionand order, and the size of the clip database (note that new video clipscan be continually added to the database). Also, the playlist of videosthat is generated for a user can be saved and shared by that user withyet other users (e.g., members of an online social network site or otherforms of sharing).

In one embodiment, a system to generate exercise videos (or other formsof content in alternative implementations) consists of a database thatstores video clips with associated meta-tags, software logic thatselects clips from the database and arranges them in an order forpresentation/play to a user, and a video player that displays theplaylist of clips as a seamless video to the user on a user device(e.g., iPad). The meta-tags are descriptors of key attributes of theindividual video clips. In an exercise implementation, the meta-tags mayinclude, for example, gender of the instructor, number of caloriesburned doing an exercise, muscle groups that are worked by an exercise,etc. The interface presented to the user of the application permits theuser to specify values or ranges for these different attributes. Forinstance, using a graphical “slider,” an end user may specify an upperand lower value for the number of calories that the user wants theplaylist of videos to burn. For example, after a user has entered all ofthe user's preferences or requirements, all matching video clips arepulled from the database. If there are not enough matching videos to theuser's requirements, the user is prompted to broaden the requirements.If there are more video clips than are needed, a secondary mechanism maybe used to select which clips are chosen for the playlist. Thesesecondary mechanism attributes may, for example, favor the most popularvideos in the selection, the newest videos, or ones that the user hasnever seen before.

Additional features can be added to this system such as the ability tosave and share workout videos. The system can support applications on awide range of user devices (e.g., smart phones, tablets, PCs, and smartTVs).

FIG. 1 shows a system for generating a video playlist according to oneembodiment. In FIG. 1, user terminals (e.g., 141, 143, . . . , 145) areused to access a server 123 over a communication network 121. The server123 may include one or more web servers (or other types of datacommunication servers) to communicate with the user terminals (e.g.,141, 143, . . . , 145).

The server 123 is connected to a data repository 129 to store, forexample, video clips in a video database 131 and user parameter data135. Each user terminal may request that server 123 generate one or morevideo playlists. For example, user terminal 145 includes video player150 that can be used to play video playlist 152. Video player 150 maybe, for example, a software application downloaded from an onlinemarketplace such as Apple iTunes or Google Play. Video player 150 may beincorporated as part of this downloaded application, and video playlist152 may have been previously generated by and received from server 123.User terminal 145 may be, for example, an Apple iPad or a mobile devicebased on the Android operating system.

In one embodiment, as discussed in more detail below, a softwareapplication on user terminal 145 is used by a user to provide userparameter data 135 to server 123. Parameter data 135 includes parametersfor a video playlist that the user desires to generate. Server 123includes content engine 125, which uses user parameter data 135 andother software logic as discussed below to generate a video playlistusing one or more video clips obtained from video database 131 (notethat other data sources may be used instead of or in addition to datarepository 129). The software logic may be contained within software ofcontent engine 125. In one example, the video playlist is an exercisevideo that provides the user with a fitness workout or other exerciseregimen. However, in other embodiments, the playlist may present videosor other content for activities other than exercise.

In one embodiment, video database 131 stores both video clips and metadata. Specifically, in this embodiment, the meta data consists ofmeta-tags associated with each of the video clips. The meta-tags can bebasic (e.g., length, title, etc.) or application-specific (e.g., fitnessinstructor, workout equipment used, calories burned, body partexercised, intensity, etc.). For example, the video clips may beobtained from third party sources and/or from users such as fitnessprofessionals that provide video clips for storage in video database131. The meta-tags may have been previously associated with the videoclips by the provider of the video clips, and/or the meta-tags may beassociated by the operator of server 123.

Although FIG. 1 illustrates an example system implemented in clientserver architecture, embodiments of the disclosure can be implemented invarious alternative architectures. For example, the server 123 can beimplemented via a peer to peer network of user terminals, where thevideo playlists are shared via peer to peer communication connections.For example, content engines may be implemented in the individual userterminals, instead of running on one or more centralized servers.

In one alternative embodiment, the software application downloaded touser terminal 145 may be used to locally generate the video playlistusing a video database stored on, or otherwise accessed locally by, userterminal 145. Server 123 is not involved in this local playlistgeneration. However, locally-generated playlist may still be sent toserver 123 for storage and potential sharing with others such as socialnetwork friends of the user.

In some embodiments, a combination of client server architecture andpeer to peer architecture can be used, in which one or more centralizedservers may be used to provide some of the information and/or servicesand the peer to peer network is used to provide other information and/orservices. Thus, embodiments of the disclosure are not limited to aparticular architecture.

FIG. 2 shows a screen shot displayed by a playlist generationapplication according to one embodiment. This playlist generationapplication is an example of the downloaded software applicationdiscussed above, and is downloaded to, for example, an iPad device 242.The playlist generation application may generate the playlist with orwithout interaction with server 123 as discussed above.

More specifically, a graphical user interface (GUI) of this application,as illustrated in FIG. 2, permits a user to choose parameters that willbe used to dynamically generate, for example, workout video playlist152. These parameters form part or all of the user parameter data 135discussed above.

In FIG. 2, the user uses a window or region 244 of the displayed screento manually select exercise equipment that the user desires for useduring exercise. This equipment may be, for example, a mat, an exerciseball, and/or dumbbells. The user also uses a window or region 246 tospecify one or more desired trainers to appear in some or all of thegenerated playlist 152. Also, the user specifies the desired totalduration or time length of the new playlist using an entry field 248.The information provided in windows 244 and 246, along with entry field248, form part of the user parameter data 135.

After the user has provided parameters for the desired video playlist,the user initiates the playlist generation process by touching,clicking, or otherwise activating a user icon 250. Alternatively, theuser may activate a link 252 to generate the playlist. Link 254 providesthe user access to an online store where the user may view, share,and/or purchase video playlists created by the user or other persons orentities.

FIG. 3 shows a playlist generated using the generation application ofFIG. 2 according to one embodiment. The application (sometimes referredto herein simply as an “app”) is used to arrange, for example, exercisevideo clips into a playlist. The video clips 302 selected for thegenerated playlist are presented to the user in a preview form on thescreen of device 242. The exercise equipment needed by the user for useduring the activities presented in video clips 302 is presented ordisplayed in a window region 306. The actual time duration of thegenerated playlist is presented in a field 304. The user may activatevideo player 150 using button 308.

After activation by the user, video player 150 displays the playlist ofclips 302 generated by the software logic as a seamless video. Theapplication may also display supplementary information, such as theremaining time, the exercise title, the upcoming exercise in the nextvideo clip in sequence to be played, etc.

FIG. 4 shows a method to generate a playlist according to oneembodiment. As discussed above, software logic is used to generate thevideo playlist 152. The software logic may be contained in thedownloaded software application and/or at server 123 in content engine125. The method shown in FIG. 4 is implemented by this software logic.

More specifically, in block 401, user-defined parameters are receivedfrom a user via a user interface of a user terminal. These parametersmay form some or all of user parameter data 135 to be transmitted toserver 123, or such data may be used only for local processing.

In block 403, video clips are selected from a database based on theuser-defined parameters, and further based on meta data for video clipsstored in the database. This metadata may consist of or include theassociated meta-tags discussed above.

In block 405, the selected video clips are arranged into a playlist forproviding to the user. In block 407, if the playlist is generated at aserver, the playlist is transmitted to a user terminal. In block 409,the generated playlist is displayed to the user on a display of a userterminal 145.

In one embodiment, the software logic that implements the method of FIG.4 takes user-defined inputs as parameters, selects appropriate videoclips from the database, and arranges the clips into an orderedplaylist. The logic uses meta-tags stored in the database to filter,select, and arrange these video clips.

In this embodiment, three primary processes are implemented by thesoftware logic, as discussed below. The first primary process implementsa filter based on the user-defined parameters. More specifically, thisprocess simply filters video database 131 to provide a filtered datasetthat meets certain of the user-defined parameters. Only some of theuser-defined parameters are considered in this filtering process. Forexample, in the software application downloaded to user device 242,parameters such as “fitness instructor” and “available exerciseequipment” serve as filters in this process, whereas the parameter“desired playlist time duration” does not. Additional parameters used inthis filtering may include, for example, “intensity”, “level”, etc.

The next two primary processes act on the filtered dataset obtained fromthe first primary process discussed immediately above. The secondprimary process implements a playlist structure and distribution ofvideo clips. This second process determines the underlying structure ofthe playlist and considers the user-defined “time duration” parameter(e.g., as provided in entry field 248 of FIG. 2) along with theassociated meta-tags for the video clips in database 131. The underlyingstructure of the playlist is defined by the percentage distribution ofvideo clips from an arbitrary set of meta-tags. As one example, thearbitrary set in this context may mean the chosen set of attributesdeemed appropriate for this application. For instance, in a contextwhere the user picks courses for a meal to be prepared, and theapplication creates an integrated “how to” cooking video, the “arbitraryset” may include, for example, calories, difficulty in preparation, useof certain ingredients, etc.

As implemented using the playlist generation application, this secondprimary process evenly distributes exercise video clips into each ofseveral groups in the generated video playlist, for example such asmajor muscle groups (e.g., clips having associated meta-tags:“upper-body”, “lower-body”, and “core”). Warm-up and warm-down periodsmay also be defined in this process. For example, the desired structuremay be governed by the programming itself based on the domain of theapplication. For instance, in a workout application, there is a certainordering that an expert will define that the user should do for a givenset of workout steps. That ordering is programmed into the application.As another instance, the ordering might be a progression from easy tohard workout steps, or the ordering might rotate muscle groups. In thecontext of a cooking application, the ordering may be driven by how longeach cooking step takes, etc.

In one embodiment, the final underlying structure is described in termsof percentage of total time (e.g., either a percentage of total desiredtime defined by the user, or a percentage of the actual total time ofthe generated playlist). One example of an underlying structure is asfollows: 15% warm-up|20% upper-body|25% lower body|25% core|15%warm-down. In some cases, a broad definition of the meta playlist may becoded into the application so that, for example, the resulting videoplaylist is not dangerous, impossible, unreasonable, etc.

For each, for example, muscle group, video clips are drawn from thefiltered dataset (from the first primary process above), and arrangedrandomly or pseudo-randomly, or otherwise arranged with some variabilityto avoid exact repetition. Additional software logic may be used toallow for reasonable repetition of video clips and to make morefine-tuned adjustments to the order of clips (e.g., based on one or morerules such as, for example, “clip B must always follow clip A”).

A variety of underlying structures for playlists may be defined withinthe playlist generation application. For example, a playlist structuremay gradually increase intensity throughout the workout, or evenly mixPilates and yoga exercises. In some cases, the structure is broadlypre-determined based on consultation with an expert, and the nuances andparticulars are determined by the application based on the user'spreferences.

The third primary process implements parameter-based limits (e.g.,limits based on other of the user-defined parameters not used in thefirst primary process above). More specifically, certain user-definedparameters establish limits for the video clip playlist. The mostdominant example is the “time duration” parameter (e.g., provided by theuser in entry field 248 of FIG. 2). The final playlist is generated tobe close to or identical to this “time duration” limit. In other cases,such as in a cooking example, there is no time duration. If the userpicks a turkey, dressing, green beans, etc., that the user wants to eatat a certain time (e.g., 6:00 PM), then the playlist of videos has theuser start earlier (e.g., at 3:45 PM) to ensure that the user completesthe cooking on time. Meals for other users may require starting at anearlier or later time.

The software logic selects the appropriate clips from the filtereddataset (taking each clip's length and overall number of clips intoaccount), and follows the underlying structure established in the secondprimary process above. Additional limits for the playlist generationapplication may be “calories burned” or “total repetitions”.

In other embodiments, users may save and share generated workout videos(e.g., playlists of clips). On a backend server, this is implemented bysaving and sharing a playlist data file. Any user who has access to anequivalent database of video clips is able to view the playlist datafile as a workout video (an equivalent database contains all of thevideo clips referenced or included in the video list; some users may nothave obtained or purchased all of the video clips found in a playlist ofanother user). A graphical user interface may be provided that permitsusers to modify existing, or create new, video clip playlists.

Various embodiments are now discussed below. In a first embodiment, amethod comprises: receiving, via input to a mobile user device,user-defined parameters; generating, by a server, an exercise videoplaylist comprising a plurality of video clips, the generatingcomprising selecting the plurality of video clips from a data repositorybased on the user-defined parameters and further based on meta data forvideo content stored in the data repository; and sending, by the server,the playlist for display on the mobile user device.

In one embodiment, the playlist is displayed by a video player on adisplay of the user device. In one embodiment, the content stored in thedata repository is video clips, and the meta data comprises associatedmeta-tags for each of the video clips.

In one embodiment, the generating the playlist comprises determining anunderlying structure of the playlist, and arranging the video clips tobe consistent with the underlying structure. In one embodiment, theplaylist comprises links to the content portions. During playing of theplaylist, the videos are accessed using the links.

FIG. 5 shows a block diagram of a data processing system which can beused in various embodiments. While FIG. 5 illustrates various componentsof a computer system, it is not intended to represent any particulararchitecture or manner of interconnecting the components. Other systemsthat have fewer or more components may also be used.

In FIG. 5, the system 201 includes an inter-connect 202 (e.g., bus andsystem core logic), which interconnects a microprocessor(s) 203 andmemory 208. The microprocessor 203 is coupled to cache memory 204 in theexample of FIG. 5.

The inter-connect 202 interconnects the microprocessor(s) 203 and thememory 208 together and also interconnects them to a display controllerand display device 207 and to peripheral devices such as input/output(I/O) devices 205 through an input/output controller(s) 206. Typical I/Odevices include mice, keyboards, modems, network interfaces, printers,scanners, video cameras and other devices which are well known in theart.

The inter-connect 202 may include one or more buses connected to oneanother through various bridges, controllers and/or adapters. In oneembodiment the I/O controller 206 includes a USB (Universal Serial Bus)adapter for controlling USB peripherals, and/or an IEEE-1394 bus adapterfor controlling IEEE-1394 peripherals.

The memory 208 may include ROM (Read Only Memory), and volatile RAM(Random Access Memory) and non-volatile memory, such as hard drive,flash memory, etc.

Volatile RAM is typically implemented as dynamic RAM (DRAM) whichrequires power continually in order to refresh or maintain the data inthe memory. Non-volatile memory is typically a magnetic hard drive, amagnetic optical drive, or an optical drive (e.g., a DVD RAM), or othertype of memory system which maintains data even after power is removedfrom the system. The non-volatile memory may also be a random accessmemory.

The non-volatile memory can be a local device coupled directly to therest of the components in the data processing system. A non-volatilememory that is remote from the system, such as a network storage devicecoupled to the data processing system through a network interface suchas a modem or Ethernet interface, can also be used.

In one embodiment, a data processing system as illustrated in FIG. 5 isused to implement server 123, and/or an online network site, and/orother servers, such as a server to store and share video playlists forsharing.

In one embodiment, a data processing system as illustrated in FIG. 5 isused to implement a user terminal. A user terminal may be in the form ofa personal digital assistant (PDA), a smart phone, a tablet computer, acellular phone, a notebook computer or a personal desktop computer.

In some embodiments, one or more servers of the system can be replacedwith the service of a peer to peer network of a plurality of dataprocessing systems, or a network of distributed computing systems. Thepeer to peer network, or a distributed computing system, can becollectively viewed as a server data processing system.

Embodiments of the disclosure can be implemented via themicroprocessor(s) 203 and/or the memory 208. For example, thefunctionalities described can be partially implemented via hardwarelogic in the microprocessor(s) 203 and partially using the instructionsstored in the memory 208. Some embodiments are implemented using themicroprocessor(s) 203 without additional instructions stored in thememory 208. Some embodiments are implemented using the instructionsstored in the memory 208 for execution by one or more general purposemicroprocessor(s) 203. Thus, the disclosure is not limited to a specificconfiguration of hardware and/or software.

Additional exemplary networked and distributed environments, and anexemplary computing device, are described in United States PatentApplication Publication US 2009/0092124, published Apr. 9, 2009 (titled“NETWORK ROUTING OF ENDPOINTS TO CONTENT BASED ON CONTENT SWARMS”;inventors Singhal et al.; assignee Microsoft Corporation; applicationSer. No. 11/866,811, filed Oct. 3, 2007), which is hereby incorporatedby reference in its entirety.

FIG. 6 shows a block diagram of a user device according to oneembodiment. In FIG. 6, the user device includes an inter-connect 221connecting the presentation device 229, user input device 231, aprocessor 233, a memory 227, a position identification unit 225 and acommunication device 223.

In FIG. 6, the position identification unit 225 is used to identify ageographic location for user content created for sharing. The positionidentification unit 225 may include a satellite positioning systemreceiver, such as a Global Positioning System (GPS) receiver, toautomatically identify the current position of the user device.

In FIG. 6, the communication device 223 is configured to communicatewith an online social network to provide user data. The user inputdevice 231 may include a text input device, a still image camera, avideo camera, and/or a sound recorder, etc.

In one embodiment, the user input device 231 and the positionidentification unit 225 are configured to automatically tag user datacontent created by the user input device 231 with navigation informationidentified by the position identification unit 225.

In this description, various functions and operations may be describedas being performed by or caused by software code to simplifydescription. However, those skilled in the art will recognize what ismeant by such expressions is that the functions result from execution ofthe code by a processor, such as a microprocessor. Alternatively, or incombination, the functions and operations can be implemented usingspecial purpose circuitry, with or without software instructions, suchas using an Application-Specific Integrated Circuit (ASIC) or aField-Programmable Gate Array (FPGA). Embodiments can be implementedusing hardwired circuitry without software instructions, or incombination with software instructions. Thus, the techniques are limitedneither to any specific combination of hardware circuitry and software,nor to any particular source for the instructions executed by the dataprocessing system.

While some embodiments can be implemented in fully functioning computersand computer systems, various embodiments are capable of beingdistributed as a computing product in a variety of forms and are capableof being applied regardless of the particular type of machine orcomputer-readable media used to actually effect the distribution.

At least some aspects disclosed can be embodied, at least in part, insoftware. That is, the techniques may be carried out in a computersystem or other data processing system in response to its processor,such as a microprocessor, executing sequences of instructions containedin a memory, such as ROM, volatile RAM, non-volatile memory, cache or aremote storage device.

Routines executed to implement the embodiments may be implemented aspart of an operating system, middleware, service delivery platform, SDK(Software Development Kit) component, web services, or other specificapplication, component, program, object, module or sequence ofinstructions referred to as “computer programs.” Invocation interfacesto these routines can be exposed to a software development community asan API (Application Programming Interface). The computer programstypically comprise one or more instructions set at various times invarious memory and storage devices in a computer, and that, when readand executed by one or more processors in a computer, cause the computerto perform operations necessary to execute elements involving thevarious aspects.

A machine readable medium can be used to store software and data whichwhen executed by a data processing system causes the system to performvarious methods. The executable software and data may be stored invarious places including for example ROM, volatile RAM, non-volatilememory and/or cache. Portions of this software and/or data may be storedin any one of these storage devices. Further, the data and instructionscan be obtained from centralized servers or peer to peer networks.Different portions of the data and instructions can be obtained fromdifferent centralized servers and/or peer to peer networks at differenttimes and in different communication sessions or in a same communicationsession. The data and instructions can be obtained in entirety prior tothe execution of the applications. Alternatively, portions of the dataand instructions can be obtained dynamically, just in time, when neededfor execution. Thus, it is not required that the data and instructionsbe on a machine readable medium in entirety at a particular instance oftime.

Examples of computer-readable media include but are not limited torecordable and non-recordable type media such as volatile andnon-volatile memory devices, read only memory (ROM), random accessmemory (RAM), flash memory devices, floppy and other removable disks,magnetic disk storage media, optical storage media (e.g., Compact DiskRead-Only Memory (CD ROMS), Digital Versatile Disks (DVDs), etc.), amongothers. The computer-readable media may store the instructions.

The instructions may also be embodied in digital and analogcommunication links for electrical, optical, acoustical or other formsof propagated signals, such as carrier waves, infrared signals, digitalsignals, etc. However, propagated signals, such as carrier waves,infrared signals, digital signals, etc. are not tangible machinereadable medium and are not configured to store instructions.

In general, a tangible machine readable medium includes any mechanismthat provides (e.g., stores) information in a form accessible by amachine (e.g., a computer, network device, personal digital assistant,manufacturing tool, any device with a set of one or more processors,etc.).

In various embodiments, hardwired circuitry may be used in combinationwith software instructions to implement the techniques. Thus, thetechniques are neither limited to any specific combination of hardwarecircuitry and software nor to any particular source for the instructionsexecuted by the data processing system.
